Yaskawa Error Code: A910 Link

Check for short circuits or ground faults in the main circuit cables. Evaluate Motor/Drive Capacity

The keyword "LINK" in A.910 LINK refers to the communication architecture that connects the Yaskawa drive to a higher-level controller, usually via fieldbus. While A.910 itself is an , communication-related errors like A.960 (MECHATROLINK communications warning) and bUS (Option Communication Error) often occur simultaneously or through cascading failures. A common pattern is an unstable communication network causing erratic torque commands, leading to a mechanical overload and triggering A.910 . In such cases, you must:

| Scenario | Recommended Action | | :--- | :--- | | | Perform an Autotune (Tune the motor parameters). This ensures the drive knows the exact electrical characteristics of the motor. | | Genuine Overload | 1. Reduce the mechanical load. 2. Increase acceleration time (C1-01, etc.) to reduce current spikes during start. 3. Consider replacing the motor with a larger frame size. | | Cyclic Loads | If the load pulses (e.g., a press machine), the RMS current might be fine, but the peak current triggers the alarm. Adjust the L3-03 (Overload Limit Level) . | | Warning Annoyance | If the operator is aware of the load and wishes to ignore the warning (not recommended), parameter L3-01 can be changed from "Enabled" to "Disabled" (Value 0), provided external thermal protection exists. |

Yaskawa error code A.910 Overload Warning that appears on Sigma series servo drives

Rapidly reversing directions with heavy, high-inertia loads. 4. Poorly Adjusted Overload Warning Levels ( Pn52B )

Check parameter Pn52B (Overload Warning Level). This parameter dictates at what percentage of the absolute maximum load the A.910 warning should flag. If it is set abnormally low (e.g., 20% or 30%), it triggers prematurely. Check for short circuits or ground faults in

Ensure the cooling fans in the control panel are functional and that the ambient temperature remains within the specified range (typically below 55 raised to the composed with power cap C Evaluate Hardware

On the next quiet night shift, Lin reopened the binder and read the A910 entry. In the margin she had written a small note: "Listen for patterns. Machines lie in timing." A common pattern is an unstable communication network

Check for tight spots, resistance, or grinding noises along the entire length of travel. Re-lubricate components or realign linear rails if binding is detected. Step 2: Review and Adjust Parameter Pn52B

An overload warning is rarely an isolated electrical failure. Instead, it is typically a mechanical or configuration issue manifesting as excessive current draw on the servo pack. The core triggers behind the A.910 error span four technical categories: 1. Mechanical Binding and System Friction
